sHINcLE-STRIP.'

SPECIFICATION forming part of Letters Patent N o. 685,102, dated October 22, 1901.

Application led March 5,1901. Serial Nat 49,884.. (No model.)

To a/ZZ whom, t nuty concern:

Be it known that I, FEANcIs N. CHRESTIEN, a citizen of the United States of America, residing at Camden, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Shingle- Strips, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to an improvement in shingle-strips; and it consists in the mechanism hereinafter more fully pointed out and claimed.

The purpose of my invention is to provide air-spaces under the shingles between the courses on the roof ofA buildings for prolonging their usefulness, which is accomplished by the arrangement of the mechanism hereinafter more fully pointed out and claimed.

In the drawings, Figure 1 illustrates a section of a roof on a building, broken lines indicating parts removed. The ligure shows a section in perspective.y Fig. 2 is a vertical section of a portion of a roof of a building, showing the location and arrangement of my corrugated metal strips between the courses of shingles.

Having described my invention with reference to the figures, I will now proceed to describe the same more in detail.

It is a well-known fact with almost all roofs where shingles are used that the character of such shingles is what is known in the trade as sawed shin gles,which,when laid in courses, are brought very closely together, so much so that air is not permitted to pass freely between the different courses of shingles, which shingles will last very much longer if arrangements are provided for permitting air-spaces between the different courses of shingles.

In the drawings, l represen ts the roofboards.

2 represents the courses of shingles on the roof, and 3 represents a metal strip corrugated 1crosswise of its length which permits the water or moisture which may workthrough the outer course to pass either under or above the metal strip and leaves a space between the courses of shingles both above and below the corrugated metal strip, which corrugated metal strip engages alternately with the upper and lower course of shingles, so that a space is left under and over the corrugated strip on the courses of shingles which prevents the moisture from being dammed or retained and at the same time permits the passage of air freely both above and below the corrugated metal strip between the courses of shingles. The metal strip is nailed to the under course of shingles, as indicated at et.

By the arrangement ofthe parts as here illustrated and shown the shingles laid with the corru gated metal strip between the courses will prolong the life and utility of the roof at least one-third.

The form and shape ofthe corrugated strip maybe somewhat modified; but in such modification it is important to have bearing-points between the layers of shingles to prevent the damming orholding of moisture between the upper and lower courses of shingles and the exclusion of air between the courses of shingles for drying out the moisture.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-` 1. The corrugated metal strip arranged and secured between the courses of shingles in the manner and for the purposes specified.

2. The corrugated metal strip corrugated crosswise of its length combined with layers of shingles located above and below the corrugated strip for the purposes stated.

3. In the shingle roof having a succession of layers of shingles the combination therewith of metal strips having a succession of elevations and depressions located between the layers of shingles for the purposes stated.

In testimony whereof I afdx my signature in presence of two witnesses.

FRANCIS N. CHRESTIEN.
